NAND, INV, CMOS, HCMOS logic series - are there models in LTSPICE?

 

As the subject say: I'd like to use some NAND gates like 74HCT03. Is there a library available in LTSPICE from somewhere?

Hello Cristoph

If it's just "gates like ...", then you have the directory [Digital],
with A-devices (see the manual for more details, and ltwiki.org for
even more). If it's a CMOS or the likes you're looking for, there are
some libraries in the group's Files area, or, you can always build one
from scratch, yourself, with NMOS4 and PMOS4 readily available.

Download and save all_files.htm from the web site and open it in your browser. Search (CTRL-F) for likely keywords, such as CMOS.

Hello Christoph,

There is a library with HC and HCT in our group's directory Files > Lib.

Models: 74HCT.lib
Symbols: 74HCT.zip
Please although take a look to the examples from this folder.

It's best practice to copy the symbols(.asy) you need to the folder of your schematic. Although copy the file 74HCT.lib into this folder. Please be ware that these models are somewhat idealized. This means they may behave better than the real parts especially regarding output drive capability.
?
Best regards,
Helmut
